## Quick context for LLMs

- **Who**: 19-year-old AI developer from New Delhi, India. I build (& break) things.
- **Known for**: Creator of Claurst (Claude Code ported to Rust — 7k stars in its first week, 10k+ now), Backdooms (DOOM in a QR code) and 50+ shipped projects. Writes MindDump (50-100k monthly readers).
- **Machine-readable data**: https://kuber.studio/profile.json — JSON snapshot of identity, skills, projects, achievements, and press.
- **Blog + RSS**: https://kuber.studio/blog/ — full index at https://kuber.studio/blog/llms.txt (RSS: https://kuber.studio/blog/index.xml). The blog's own llms.txt is always the freshest source for posts, and the blog runs an MCP server at https://minddump-mcp.kuberhob.workers.dev/mcp.

## Short bio

Hi! I'm Kuber Mehta (kuberwastaken), an AI developer from New Delhi, India.

I'm studying Computer Science & Machine Learning at BITS Pilani and AI & Data Science at IP University.
I'm currently part of [Razorpay's](https://razorpay.com) Central AI team in the Founders' Office, where we primarily build foundational models ([Vulcan](https://razorpay.com/blog/vulcan-how-razorpay-built-a-foundation-model-for-payment-decisions/)) and agent-to-agent (A2A) systems. Alongside that, I work on generative UI for LLMs, world-model caching, and more at [PolyThink Labs](https://www.polyth.ink/).

Chances are, you've come here after seeing one of my projects. Most of them start as an intrusive idea and turn into what I call a SideQuest — run Projects to see some of my favorites.

I also write a blog named MindDump now at 50-100k readers per month.

Previously: Business Fellow @ Perplexity, AI Summer Resident @ Nas Daily (Dubai), AI Agents Websocket Framework LEAD Intern @ HTMX (thanks Twitter)

Fun Fact: I started making games on Roblox when I was 12, made over 1 Million Robux by 14, at 16 I got into 3D modelling and won India's biggest student contest for it, and I almost went to culinary school at 17 because I sucked at math - glad it worked out though :)

At my core, I love Building (& Breaking) things, so if you're making something cool and ambitious, reach out via twitter or linkedin.
